google maps API v3 set marker and get point

I have a problem to set marker and get latitude and longitude for that marker. How can I do that in google maps v3 API

var myLatlng = new google.maps.LatLng(-34.397, 150.644);
        var myOptions = {
          zoom: 8,
          center: myLatlng,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
var map = new google.m开发者_StackOverflowaps.Map(document.getElementById("divGoogleMaps"), myOptions);

google.maps.event.addListener(map, 'click', function() {

});

this is my start code.

You should check Google Maps API doc web-site they have a fex example to help you started.

http://code.google.com/apis/maps/documentation/javascript/basics.html

google.maps.event.addListener(map, 'click', function(e) {
          placeMarker(e.latLng, map);
        });
      }

      function placeMarker(position, map) {
        var marker = new google.maps.Marker({
          position: position,
          map: map
        });
        map.panTo(position);
      }

Here you set a marker and get the position.

var marker = new google.maps.Marker({
  position: myLatlng, 
  map: map, 
  title:"Hello World!"
}); 

Taken directly from Google Maps API v3

If you want to attach an event listener to the marker, it is advisable to do it right after you add it to the map, while you still have a fresh reference to it (in the case where you're potentially looping through some marker adding code, as is common).
